A gimbal stabilizer is a tool that uses motors and smart sensors to support and stabilize a camera; you can shoot smooth video footage while you are moving. It illuminates sudden movement and shakes. Modern gimbals utilizing quiet brushless motors that make micro-adjustments to the arms of the gimbal, so the mounted camera can be completely steady.

In this post, I will explain the gimbal stabilizing system and recommend some types for both DSLR cameras and smartphones camera.

Definition: By Wikipedia

A gimbal is a pivoted support that allows the rotation of an object about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first animation). For example, on a ship, the gyroscopes, shipboard compasses, stoves, and even drink holders typically use gimbals to keep them upright with respect to the horizon despite the ship’s pitching and rolling.

Handheld 3-axis gimbals are used in stabilization systems designed to give the camera operator the independence of handheld shooting without camera vibration or shake.

Why we use a gimbal

A nice cup of tea, for example, will spill its contents if you tilt it at a certain angle. Turn it over, and you can expect everything inside to fall on the floor.

However, if you put the cup on a gimbal, then it remains at an upright position, regardless of how you are holding the base of the gimbal or its outer circle. The cub’s roll, pitch, and yaw axes make instant adjustments to counter shake, jolts, and other movements. Thus, the cup always remains horizontality leveled and never spills its content.

That is why we use the gimbal with a camera, especially when shooting videos. Your camera will always remain steady and horizontally level in spite of your movement.

How gimbal works

The 3 axis gimbal, as the name implies, adjust and stabilizes the three known movement axis: tilt, pan, and roll of a camera to maintain the camera in a horizontal position.

A shaking camera will obviously have random unwanted movement in all three axes. However, it is possible to effectively counteract those movements by producing movements in the opposite direction. Essentially, the gimbal does the exact opposite pitch, yaw and roll movements so you have a perfectly stable camera. The three main axes are shown in the below photo.

gimbal axes

  • Tilting (Pitch axis) is moving up and down. This feature of a camera stabilizer is used to take a video of an object moving up and down or vice versa. Taking a video of a person going down and up the stairs or a person jumping into a swimming pool are examples of the movement along the tilt axis.
  • Panning (Yow axis) is moving from left to right and vice versa. This feature of the gimbal stabilized the camera movement when following an object moving horizontally. Like a moving car or a running person.
  • The roll is the tracking of somebody when he is rotating about an axis that is perpendicular to the vertical plane

Types of Gimbals

There are two versions of gimbal stabilization systems:

Mechanical Gimbal

Mechanical gimbal

Mechanical gimbals have the sled, which includes the top stage where the camera is attached, the post that in most models can be extended, with the monitor and batteries at the bottom to counterbalance the camera weight. This is how the Steadicam stays upright, by simply making the bottom slightly heavier than the top, pivoting at the gimbal. This leaves the center of gravity of the whole rig, however heavy it may be, exactly at the operator’s fingertip, allowing deft and finite control of the whole system with the lightest of touches on the gimbal.

Motorized Gimbal

Motorized gimbal

There are two common types: two and three-axis gimbals. Brushless motors (two or three motors according to its type) power the motorized gimbal; motorized gimbals have the ability to keep the camera level on all axes as the camera operator moves the camera. An inertial measurement unit (IMU) responds to movement and utilizes its separate motors to stabilize the camera. With the guidance of algorithms, the stabilizer is able to notice the difference between deliberate movement such as pans and tracking shots from unwanted shake. This allows the camera to seem as if it is floating through the air, an effect achieved by a Steadicam in the past.

How to choose a Gimbal

When you are trying to choose a gimbal, you have to keep in mind that some of them are designed solely for stabilizing your camera, while others offer many more capabilities.

These extra features can be remote controls that allow you to control the camera’s movement from a distance. Others have time-lapse video modes where you can set the camera to slowly pan while you capture time-lapse video. Another feature that can be found in some gimbals is the auto-tracking features where they can automatically keep a moving subject in the frame. Also, some of them have external rod-mount focus motor for mechanical follow focus/zoom control.

So, it very important to think about what features you really want, what types of shots you are planning to take, and finally how much many you have. The following are some general factors to be considered when choosing a gimbal:

  • Axis Stabilization: The single most important feature in a gimbal is its ability to keep your camera steady. There are two different types of gimbals – two-axis stabilizers and three-axis stabilizers. Two-axis gimbals stabilize your Tilt and Roll, and three-axis gimbals stabilize your Pan. Two-axis stabilizers are generally more affordable, but three-axis stabilizers are better for shooting moving footage.
  • Gimbal payload: It is very important to check the payload capability of your gimbal and make sure that it can handle the weight of your camera and lens
  • Batteries running time: Battery-powered gimbals come in one of two ways. Some models use standard alkaline batteries that have to be replaced in regular intervals. Others use rechargeable lithium-ion batteries, but these tend to have shorter running times.
  • Gimbal Weight: Most gimbals do not weigh more than a couple of pounds, but even two or three pounds can get heavy if you have to hold it up for extended periods. As a rule of thumb, the lighter the gimbal the better, but make sure you are not sacrificing performance just to save half a pound.
  • Compatibility: you need to make sure the gimbal you purchase is compatible with your camera or smartphone as well.
